が実施されていた。(Prior Art) Conventionally, a honeycomb structure, which is a ceramic green body structure having countless parallel through holes separated by partition walls having a substantially uniform wall thickness, is produced by extruding clay made of a ceramic material through a die. For drying, a dielectric drying method was used.

受台を提案している。However, when a honeycomb structure is dried by the above-mentioned dielectric drying method, there is a drawback that the density of electric lines of force passing through the honeycomb structure is not uniform. In order to solve this problem, the applicant proposed in Japanese Patent Publication No. 60-37382,
We have proposed a drying pedestal in which a certain area including the part where the lower end surface of the opening of the honeycomb structure contacts is made of a perforated plate having a higher conductivity than the other peripheral area.

大きくなる欠点があった。(Problem to be Solved by the Invention) When dielectric drying of a honeycomb structure is carried out using the drying pedestal described above, the density distribution of electric lines of force becomes uniform to some extent, but it is still The density is not uniform, and as a result, drying is delayed in the upper part of the honeycomb structure compared to other parts. In other words, drying shrinkage is smaller in areas where drying is delayed compared to other areas, resulting in dimensional variations between the upper and lower parts of the honeycomb structure after dielectric drying.
Dimensional accuracy decreases. That is, there was a drawback that the upper part was larger than the lower part.
